1/2 HP Crawl Space Sump System

The Liberty CSP-457 is a complete crawl space drainage system powered by a 1/2 HP motor at 115V AC. It includes a polyethylene basin and an integrated vertical float switch for automatic operation. The unit is designed to remove water from crawl spaces and similar below-grade areas.

Suited for standard residential crawl spaces

Homeowners needing automatic water removal at up to 48.0 gpm will find this system fits typical crawl space installations. Buyers who need higher flow rates at greater lift or a larger basin capacity should look at other options.

Maximum head of 34.0 ft

The pump produces a maximum head of 34.0 ft with flow rates of 48.0 gpm at 5 ft, 44.0 gpm at 10 ft, 38.0 gpm at 15 ft, and 32.0 gpm at 20 ft. This single performance curve determines whether the system can overcome the vertical lift in your installation.

Questions about this item

Should I choose the 1/2 HP model or a smaller pump for my crawl space?

The 1/2 HP motor delivers 48.0 gpm at 5 ft head and 32.0 gpm at 20 ft head, giving strong flow for typical crawl-space drainage.

What does the 34.0 ft max head mean when the pump is installed?

It means the pump can lift water up to 34.0 ft vertically; beyond that height flow stops, so measure your discharge rise before buying.

Does the 115 V 60 Hz supply limit how far I can run the discharge pipe?

Voltage does not limit pipe length; friction loss in the pipe reduces flow, so size the pipe to keep total dynamic head under 34.0 ft.
